Wipy 3 issues

[jmpratt]

My WiPy 2 just died so I'm trying to get my WiPy 3 up and running out of the box. Did the firmware upgrade so now it executes boot.py and connects to my network. Now the heartbeat LED is False after boot.py runs. I thought that was weird so I explicitly set heartbeat(true) in boot.py but it won't flash. From the REPL, it shows heartbeat(false). Any ideas what is causing the heartbeat to go false? Main.py is the default, blank version. Here's my boot.py:

# boot.py -- run on boot-up
# can run arbitrary Python, but best to keep it minimal
#
import network
import machine
from machine import SD
from machine import UART
from network import WLAN
import os
import time
import pycom

pycom.heartbeat(True)
#
# Set up WLAN
#
wlan = WLAN() # get current object, without changing the mode

ssid     = 'Mynet'
password = 'xxxxxxx'
ip       = '192.168.1.50'
net_mask = '255.255.255.0'
gateway  = '192.168.1.1'
dns      = '192.168.1.1'


uart = UART(0, 115200)
os.dupterm(uart)

def init():
    wlan = WLAN(mode=WLAN.STA)
    wlan.ifconfig(config=(ip, net_mask, gateway, dns))

def connect():
    wlan.connect(ssid, auth=(WLAN.WPA2, password), timeout=5000)
    while not wlan.isconnected():
        machine.idle() # save power while waiting
    cfg = wlan.ifconfig()
    print('WLAN connected ip {} gateway {}'.format(cfg[0], cfg[2]))

def set():
    init()
    if not wlan.isconnected():
        connect()

set()
#
# Set up server
#
#server = network.Server()
#server.deinit()
#server.init(login=('YOUR_USERNAME','YOUR_PASSWORD'),timeout=600)
#
# SD card support
#
sd = SD()
os.mount(sd, '/sd')

@jmpratt Since there is no configuration data on a WiPy that could get lost, you could try to make a complete erase using esptool.py and then reload the firmware.

@robert-hh nope. Just sitting in an expansion board 2.0. nothing connected.

@jmpratt I anything connected to P2?
